Top Features of the New Apple iPad 2

With such a dominant grasp on the tablet market, many people are wondering where Apple could possibly go with their iPad 2 that is slated for full release on 3/11. The answer to this is practically everything. This tablet is going to be lighter, thinner, more powerful, and have better ergonomics than ever. Apple realizes that they are about to be attacked in this niche market and they are ramping up the design features to stay competitive.
The iPad 2 is going to feel quite different in the hands, but in a good way. It is 33% thinner and 15% lighter than the original without sacrificing any screen size. The speaker grilles have been dramatically enlarged in the back for clearer quality sound to go along with the streamlined build. The paint scheme will be expanded with the second generation of the iPad to either black or white hard cases straight out of the box.

The internals are no less impressive with a dual core 1GHz A5 processor that claims to be nearly twice as fast as the original including graphics that are nearly nine times better. This would generally mean much more power consumption, but the battery life remains nearly identical with 10 hours of playtime. There is still the option for a Wi-Fi only edition at a significantly reduced price with the 3G version running quite a bit more expensive.
Apple took a hint from the success of their later-generation iPhones and implemented a VGA front-facing camera for their FaceTime video chat program. This allows for one of the easiest and most conventional face to face functions on the market and is sure to be a large draw. The traditional rear-facing camera is also included with 720p resolution shooting at 30 frames per second. Included in the rear facing camera is a highly responsive auto-focus with a 5x digital zoom for catching those long distance shots.
Steve Jobs himself has designed and perfected the cover for iPad 2. Apple is careful not to call this a case, but a responsive and customized cover. There is both a plastic and leather option for these Smart Covers that can be acquired during purchase of the iPad. The proximity sensors will wake and sleep the iPad whenever the protective screen flap is open or closed. It will stay firmly shut even during the jostling that can occur in a briefcase or backpack with a powerful magnetic snap to keep the sensitive touch screen safe.
If one thing can be said about Apple, it is their unwillingness to rest on their laurels when it comes to the technology race. In a market that does not change yearly, but weekly, they continue to set their sights to the future with the lighter, smaller, and faster iPad 2.

The Galaxy Tab 10.1 4G, available with either a white or dark gray plastic back, will sell through Verizon (with a two-year 4G contract) for $529.99 for the 16-gigabyte model and $629.99 for the 32-gigabyte model, said Ken Muche, a Verizon spokesman.
The wi-fi-only version of the 16-gigabyte model sells for $499.99 while the wi-fi-only 32-gigabyte version sells for $599.99.
Without a 2-year 4G-LTE data plan, the carrier will sell the 4G-capable Galaxy Tab 10.1 at iPad-3G-matching prices that are $100 more than than with a contract -- $629.99 for the 16-gigabyte model and $729.99 for the 32-gigabyte model, Verizon's website said.
Meanwhile, some owners of the Motorola Xoom tablet may be feeling a bit burned right about now. The Xoom went on sale through Verizon in February with 3G connectivity and the promise of a soon-to-come free 4G-LTE upgrade from Motorola and Verizon (which will eventually require Xoom owners to mail in their tablets to get 4G antennas installed).
Well, it's now July and the 4G upgrade for the Xoom still hasn't rolled around. No word yet from Verizon or Motorola as to when the Xoom is expected to catch up to the Galaxy Tab in the 4G regard.
The Galaxy Tab 10.1 runs Android 3.1, or Honeycomb, and its display size is similar to the 9.7-in. iPad.
The 10.1 is 8.6 millimeters thick, a bit smaller than the 8.8 mm iPad, making it the thinnest tablet on the market. It's also the lightest model at 1.25 lbs.
LTE is potentially a big selling point for the Galaxy Tab 10.1. The system is designed to provide download speeds of 5 to 12 Mbps and upload speeds of 2 to 5 Mbps in Verizon's LTE coverage areas.
The LTE versions also support Wi-Fi networks.

Wholesale Electronics News - Battery life has been another thorn in the iPhone’s side

The Apple rumor mill went into high gear this week, spinning out this gem: Apple ordered 15 million iPhone 5 units from manufacturer Pegatron in time for a fall launch. Apple already unveiled iOS 5 at its worldwide developers conference earlier this year, which leaves only the iPhone 5 hardware as the real mystery.
Smartphones generally balance performance, battery life and size, and I’m hoping the iPhone 5 will lean toward better performance. The growth of performance-hungry apps such as augmented reality ones have been stunted under the current iPhone hardware. You can’t run more than two apps without running into performance headroom problems.
“If you want to navigate while listening to music, the phone will struggle with that,” says tech analyst Rob Enderle. “Once we have some performance headroom, you’ll likely see the shift to even thinner devices again.”
Other Business News:
Battery life has been another thorn in the iPhone’s side. The poor battery life has spawned an industry of battery-booster products, as well as tips on preserving battery life. Even worse, the iPhone battery is in a constant state of decay and will eventually need to be replaced. Yet Apple has made swapping a new battery a difficult, if not impossible, process by locking down the casing with tamper-resistant pentalobular screws.
“In short, the three vectors – performance, battery life and size – are far from ideal,” Enderle says.
There’s a good chance Apple will make small hardware improvements to the iPhone 5, such as improving the screen and glass design to prevent breakage. The iPhone 4 has been criticized for cracking easily.
"The iPhone 4 breaks more," says Kyle Wiens, CEO of iFixit, a Website that provides free repair manuals and advice forums mostly aimed at Apple products. (Check outCracking the Case of the Troublesome iPhone 4 Glass.)
On the flipside, a case can be made that the smartphone hardware may be reaching a point of diminishing return – that is, the iPhone’s hardware no longer being worth the jacked-up price tag. Consider the ubiquitous desktop: Truth is, few “power” users came close to using the full potential of these pimped out machines.
We already know that the sheer volume, for example, of apps on the App Store is a poor indicator of the quality of the store. I once thought about putting together a list of the worst iPhone apps, a counter-story to my list of 15 best iPhone apps for newbies. But where do you start? There are a lot of really dumb apps out there.
This issue of quality is exactly what comes to mind admidst the recent chatter that Apple might be leaning toward a slimmed-down iPhone, forsaking performance and battery size. The thinking goes that consumers want a more convenient phone (think: iPod Nano) that runs only a few of their most important apps.
Could Apple deliver a slimmed-down iPhone that’s more powerful than the iPhone 4? “It would be nearly impossible to do both given the current technology,” Enderle says. “Still, Apple does do things that have seemed impossible, and that would be the home run.”

Samsung makes the bold claim Notebook Series 9 is the best

If you're after for a laptop that will add the least heft to your cabin bag, there are few notebooks more desirable at the moment than Samsung's Notebook Series 9 -- it definitely punches above its weight.
The Korean electronics collossus may be better known for home theatre, but it has used its engineering prowess in making TVs ultra-thin to create one of the most impressive Windows laptops we've seen.
Samsung makes the bold claim that it is the best in terms of weight and size among notebooks that use the very latest "Sandy Bridge" class of Intel Core chips, and we haven't yet seen a laptop to disprove it.
It also has gorgeous looks -- brushed gunmetal grey, made of real metal, not plastic faux-metal.

Size and weight

The Series 9 tips the scales at 1.31KG and is only 1.63cm at its thickest point.
Its casing is built from Duralumin, a lightweight material used in making aircraft, which Samsung says is twice as strong as aluminium but just as light.

What you get

The main chip powering the notebook is the "Sandy Bridge" Intel Core i5 -- the second-generation of Intel Core technology with considerably faster performance than the first release Core i5.
However, it is one of the ultra-low voltage versions, running at 1.4GHz, which means it will not be as fast as 'full-power' Intel Core i5s used in larger notebooks. One tech comparison site ranks its speed as similar to a high-end Intel Core 2 Duo from two years ago -- so the speed of the notebook will be like full size notebooks of a 2009 vintage.
If you're after full computing speed, Toshiba's Portege R700 or Sony's new Vaio Z may be a better choice, as both ultralights use full-power Intel Core chips.
Other Business News:
Samsung hasn't let its experience in manufacturing LCD TVs go to waste -- the 13.3" display on the Series 9 notebook is a vibrant ‘SuperBright Plus’ LED-edgelit display. Like LED-lit TVs, the ultra-thin screen is able to come on instantly rather than having a few seconds warm-up time.
It has a 1366x768 pixel resolution, so it's not 'full HD' like Sony's high-end models of Vaio Z, but then, it's not $4,000, either.
Slow, mechanical hard drives have been abandoned altogether for this new breed of laptop. Samsung is instead offering it with a 128GB solid state disk (SSD) which uses very high speed flash memory with no moving parts. This means initial startup and program loading is lightning fast compared to laptops using hard drives.
Samsung says the battery-life on the Series 9 is 'three times longer' than the previous model. To its credit, Samsung doesn't claim a theoretical maximum battery-life; it uses real-life examples: 7.7 hours running the BatteryMark standard battery testing software, and 4.7 hours playing a movie.
What you don't get in such a slim package is a DVD drive -- and we think that's probably not a bad thing. With the wide availability of downloadable movies and TV shows, and super-cheap USB memory keys, the only real reason to have a DVD drive these days is for software installation, and an external USB DVD drive will do the job for these occasions.
The webcam is a 1.3 megapixel model, which will give higher image quality than laptops packing only a VGA webcam.
It only comes in one configuration, with 4GB memory installed, so if you think you'll need more than that (and most people won't) you'd have to remove RAM modules from inside the machine and get higher capacity ones installed. 4GB is plenty for good performance under Windows 7 with many apps running.

3D mapping software will be made by Microsoft, Google, and AOL

Microsoft, Google, and AOL are the subjects of a lawsuit from a company that claims the three defendants violated the patents of its 3D mapping software. Bloomberg reports that Transcenic filed the lawsuit earlier this week. The lawsuit states that the 3D software used in all three companies' street mapping services "has injured Transcenic and Transcenic is entitled to recover damages adequate to compensate for such infringement."
Google's popular Street View feature for its Map division is involved in the lawsuit along with Microsoft's Streetwise business and AOL's MapQuest division. The Lake Charles, Louisiana-based Transcenic company claims that all three companies used 3D mapping software to show its users where to go. The company claims that the software "misappropriated technology" from Transcenic. The company itself is privately owned and doesn't even appear to have its own web site. So far spokespersons for Google and Microsoft have not yet commented on the lawsuit, according to the article. AOL did not yet respond to an inquiry.
In related news. Wired.com reports that Google lost a court battle earlier this week dealing with its Street View feature. Lawsuits filed last year claimed that Google's use of vehicles to help create the Street View images "... were equipped with WiFi sniffing hardware to record the names and MAC addresses of routers to improve Google location-specific services." A judge agreed that such actions also secretly took info from people's WiFi networks and that Google can be held liable for any damages. Google has said that the use of its Street View vehicles in that way was a "mistake' and that any info taken from WiFi networks has not yet been viewed by Google.
Yay another patent troll out for some free cash, by being privately owned and not even having a website they're not actively using there patents so morally should be declared null and void
Software Patents are perfectly legitimate & a good use of the legal system, no, not a waste of time and a waste of money into the lawyers' pockets at all.

AMOLED screens impact Phone Battery Life


With AMOLED screens becoming increasingly popular on mobile phones, particularly Samsung models such as the Nexus S and Galaxy S 2, it's useful to know there's a way of reducing the impact they have on battery life.
Using Android's built-in system analysis tools, blogger Steve Mould set about discovering how much his battery was being drained by the screen itself. He then went on to find out whether using darker wallpapers, themes and apps would help to reduce power usage.
Guess what? It did.
It's worth mentioning this only works on OLED-based displays and not the currently predominant LCD/LED displays. That's because the backlight is always lit, regardless of what's being displayed. To achieve a black pixel, the light is blocked rather than turned off. In an OLED system each pixel is self-powered, which means black pixels are unlit, saving power.
Other Business News:
The most significant results were found by measuring the difference in battery usage between a Nexus S left for two hours displaying either a white or black screen. The bright screen caused the battery to drop 71 per cent compared to just 12.2 per cent for the dark screen.
If you like looking at a lot of equations, head over to the SHIFT_beeb blog and take a look. It's not an exact science, and in any case every user will get different results based on how they use their phone. If you're running a load of processor-intensive apps it don't matter if your wallpaper is black or white.
There are plenty of other ways of improving battery life. Reducing the display brightness below 50 per cent will work regardless of the screen type, as will turning off features you're not using at the time, such as Bluetooth and Wi-Fi, and ensuring background apps are behaving themselves.

Methods to care for the Li-Ion Laptop Battery

 A Li-ion battery for laptops is a battery made up of lithium – ion. To increase its life you will need to understand methods to care for the Li-Ion Laptop Battery. This battery, also referred to as LIB, comes from battery types that are rechargeable in nature. During the time of discharge, the ions of lithium move from electrodes that are negative to electrodes that are positive and return back throughout charging. In all the different kinds of LIB batteries characteristics in terms of safety, chemistry, cost as well as performance vary a lot.  Dell vostro 1520 battery
As a far as electronic items used by consumers are concerned, batteries made from lithium ion are very common. For electronic items that are portable, these rechargeable battery types are extremely popular. They are known to have the best of densities in terms of energy with absence of any effect on memory. When the battery is not being used the discharge loss is very low. Besides being used in a number of electronic items by consumers the LIBs are also popularly used in applications in aerospace, vehicles that run on electricity as well as the military field. 
The traditional battery is being researched upon where more focus is laid on intrinsic safety, durability as well as energy density of the battery, its cost as well as technology. In the past, the batteries used in laptops were very easy to charge. A circuit had to be built for voltage adjustment to ensure that charging did not exceed the capacity needed as per the mAh or the milliamp of the laptop battery. With the right kind of care for Li-Ion Laptop Battery its longevity can be improved significantly.
To get the laptop battery charged it would take a couple of hours. Life of batteries would get degraded slightly if at all if the battery underwent over charging or under charging anytime. Due to advancement in technology it is now more convenient to use the Li-ion computer batteries for laptops. As far as charging is concerned these laptop batteries, are considered the unforgiving kinds. For completing the charging cycle strict curves need to be followed in terms of voltage and charging current.  
Around three complete hours are needed for the charging of this battery which is unique to the Li-Ion variety. Current at low levels cannot be tolerated by the laptop computer batteries of the lithium ion types. For controlling the limit of current and for charging the battery a special circuit is needed especially at the time when the computer laptop battery reaches full charge. To help in regulating the charge in the laptop battery, a circuit that is sophisticated is used. Due to this, the current too gets discharged properly and the circuit in turn is able to communicate with the laptop properly about the capacity left for charging. 
It is over a particular data bus that the communication takes place. This data bus is basically tied to software dealing with the management of power that is installed in the laptop computer system. An application called Control Panel is well known to a lot of users which helps in getting an estimate on the remaining life of the battery. Minimization of consumption of power is possible as the settings within the battery help in maintaining the right kind of control. 
Features like protection of temperature levels are also present in the charging circuit in the Li-Ion Laptop Battery. Control of temperature is needed for preventing any kind of over heating or over charge. In the case of certain computer laptop batteries a thermal fuse helps in the achievement of this functionality especially when the temperature gets beyond fifty to sixty degree Celsius. A thermal sensitive resistor or a thermistor is used in other laptop battery designs. The thermistor proves to be very beneficial in communicating the temperature of the laptop battery to the circuit responsible for charging. 
Welcome to wholesaleeshop.com.au
WholesaleeShop.com.au Works with “Super Quality, Satisfactory Services”
After this communication is done, the process of charging stops especially when over heating takes place. To improve the life of the Lithium ion laptop battery, the management of temperature within the battery is very important. The advantages of lithium ion batteries are many, the reason why they are considered as the most sought after real value batteries. They are able to fit into a number of devices and power them as they come in a variety of sizes as well as shapes. As compared to other batteries which are equivalent in terms of energy, the lithium ion batteries are much lighter. 
The open circuit voltage is high as compared to batteries of the aqueous types which help in rise of power amount for enabling transfer of power to a current that is lower. The other advantage is the absence of any sort of memory effect. Batteries of nickel metal hydride have more self discharge as compared to lithium ion laptop batteries which have extremely low self discharge. Materials used for making the components of these batteries are completely environment safe. But, you need to care for lithium ion laptop batteries as rupture of cells and thermal runway can take place. Timely help and maintenance are the key requirements for any battery actually.
